T0 at whom it mag concern.-

My invention is an improvement in copying presses and consists in thenovel features of construction and combination of parts hereinafterfully described.

In the accompanying drawings I have illustrated one form in which I havecontemplated embodying my invention and said invention is fullydisclosed in the following description and claims.

In the said drawings, Figure 1 represents a side view of my improvedcopying press, the inclosing casing being shown in section. Fig. 2 is afront view of the same showing the casing in section. Fig. 3is a viewsimilar to Fig. 1 showing the parts in position just before operatingthe press. Fig. 4 is a similar view showing the press after it has beenoperated. Fig. 5 is a detail view partly in section of the adjustingmechanism for one arm of the toggle lever of the press. Fig. 6 is adetail section of a part of the device.

In the drawings A represents a casing of any desired form, provided witha top a which forms the support or bed upon which the articles to bepressed are placed.

B is the platen which is preferably hinged so that it can be raised outof the way when not in use. In order to provide for pressing copyingbooks and other material of different thicknesses the platen B is hingedto a yielding support b, which is connected to the casing by thevertical rods 6' engaging suitable guiding apertures in the top a, ofthe casing and in guide blocks (1 provided on the interior of thecasing, said rods 1) being provided with the springs b which arecompressed when the platen and its support are drawn down.

The platen may be made of metal or of wood having a reinforcing back 12of metal as shown and to the said platen are connected two links or barsC C. The links 0 C have their lower ends connected to a cross bar Dwhich is provided with trunnions d d passing through the links C C andengaging vertical guiding grooves or recesses a in the sides of thecasing. A portion d of said cross bar out of the plane of the trunnionsd dis connected by an adjustable arm E with a fixed point of resistance,as the under side of the top a of the casing. The trunnions d d of thecross bar D are preferably located adjacent to one edge of the same, andthe arm E is secured to said cross bar adjacent to the other edge sothat the cross bar and the arm E form a toggle lever. V

The cross bar D is provided with an operating lever or treadle D to beoperated ordinarily by the foot of the operator. The cross bar D whenthe press is about to be op erated as shown in Fig. 3, occupies aninclined position a little in rear of the vertical. When the lever D isdepressed the cross bar D is brought into a substantially verticalposition as shown in Fig. 4, thus straightening the toggle lever, anddepressing the trunnions d d and causing the links C C to draw down theplaten B and compress the book or other article upon the bed a of thepress. The parts will be firmly locked and held in this position by thestraightening of the toggle lever, and will remain so until the lever Dis raised. The cross bar D is provided with laterally extending lugs d dwhich engage the rear faces of the links C Cavhen the lever D isdepressed and prevent it from being pressed down too far, as shown inFig. 6.

When the press is not in use. the platen B may be raised into asubstantially vertical position out of the way, and the arms C C, thetoggle lever and operating lever D will assume the positions shown inFig. 1.

In order to give the desired amount of pressure, and to adapt the pressfor use with books, and materials of diiferent thicknesses, I providethe arm E of the toggle lever with an adjusting mechanism by which itmay be lengthened or shortened so that the platen may give the desiredpressure when the toggle lever is straightened. In this instance I haveshown the arm E formed in two parts each having a screw threaded recess2 and a screw 11 provided with right and left screw threads engagingsaid recesses. The screw is provided with a hand wheel f or other meansfor rotating the same to adjust the parts. In adjusting the parts to abook of a certain thickness the book is placed in the bed a and theplaten brought down upon the book. The lever D is then pressed down, andthe screw wheel f is turned until the press gives the desired pressureupon the book. The 1ever D is then thrown up and the press is ready tooperate without further manipulation of the screw.

It is obvious that I may provide the links C C with adjusting meansinstead of the arm E if desired and accomplish substantially the sameresult.

What I claim, and desire to secure by Letters Patent, is

1. In a copying-press, the combination with the bed and platen, of adownwardly yielding support for said platen pivotally connected thereto,links connected to said platen and extending downwardly below said bedand means connected with said links for depressing said links platen andplaten support, substantially as described.

2. In a copying-press the combination with the bed, of the support forthe platen provided with guide rods, springs normally maintaining theguide rods and support in an elevated position, the platen hinged tosaid support, the links connected to said platen and means connected tosaid links for depressing said links, platen and platen support,substantially as described.

3. In a copying-press the combination with the casing provided with thebed, of the platen, the links pivoted to said platen, a toggle-leverpivoted to the said bed and to said links, a treadle for operating saidlever, and guides controlling the movement of the lower end of saidtoggle lever, substantially as described.

4. In a copying-press the combination with the bed, of the downwardlyyielding support for the platen, the platen pivoted to said support, thelinks pivoted to said platen and extending below said bed, atoggle-lever pivoted to said bed and links, and a treadle for operatingsaid toggle-lever, substantially as described.

5. In a copying-press the combination with the casing having a bed andprovided with guiding grooves, of the platen, links pivoted to saidplaten and extending below said bed, the toggle-lever pivoted to saidbed and links and engaging said guiding grooves, and a treadle foroperating said lever, substantially as described.

6. In a copying-press the combination with the bed of a platen, linkspivoted to said platen and extending below said bed, a toggle leverpivoted to said bed and links, one arm of said lever being composed oftwo parts united by a right and left hand screw and a treadle foroperating said toggle lever, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRED H. CUTLER.
